Spline

The Spline
tools generate controlled linear environment features such as fences, walls,
paths, and repeated meshes. Use them when placement needs to follow a designed
route rather than a broad biome or volume.

Your Game Environment for the base world setup, then use spline tools for
authored linear features.

Use It When

• You need fences, walls, roads, paths, or repeated
  meshes along a route.
• You want designer-controlled placement without
  manually positioning every segment.
• You need generated content to follow a path through
  a biome, settlement, or gameplay space.

Integration Notes

• Keep spline shapes simple until the result is
  visually and mechanically stable.
• Check segment spacing, collision, and endpoint
  behavior after changing meshes.
• If the spline intersects PCG vegetation or props,
  use exclusions or filters so generated content does not fight the spline
  content.
• Validate navigation and player traversal when spline
  content becomes walls, fences, or blocking geometry.
